V 3.03
Twin Tank Wheelbarrow Portable Air Compressor
9. Breather/Oil Fill Plug
All reciprocating air compressor pumps are built with a
crankcase vent to relieve the pressure that is created by the
downward movement of the piston in the pump cylinder. Our
belt-drive units vent through the oil-fill plug. Never operate
the air compressor without the dipstick or oil-fill plug.
10. Automatic-Idle Control
This gas-powered air compressor is built with an engine idle
control kit that automatically decreases the engine speed
when the top end pressure setting of the pilot unloader valve
is reached. The top RPM setting of the engine is factory set
for maximum performance and service life. Do not alter the
factory top RPM setting. The engine idle speed is factory set
and controlled by a black plastic Philips head screw on the
carburetor. A slight increase to the idle speed setting may be
required when operating in colder temperatures. Turn screw
clockwise in 1/4-turn increments to increase the idle speed. If
the idle speed setting is too low, premature fouling of spark
plug will occur.
11. Cold-Start Valve
Our belt-driven portable units have a manual drain valve
installed on the pump aftercooler to assist with cold weather
starting. Open drain valve and allow the motor and pump to
run unloaded for a minute to warm up. Close the drain and
repeat the procedure if the motor or engine continue
to struggle.
12. Schmidt Belt-Tightening Device
The gas-powered belt-driven portable air compressor has a
unique system for maintaining proper belt tension. Simply
loosen the 1/2 in. locknuts (only until washers beneath spin
freely) that secure the engine and rotate the fine thread
bolt located on the wheel end of the base plate clockwise
until the desired belt tension is achieved. Re-tighten 1/2 in.
locknuts to secure engine and maintain desired belt
tension setting.
